Risk Factors and Clinical Implications of Double-J Ureteral Stent Bacterial Colonization

RecruitingN/A

Sponsor: Al-Azhar University

Conditions: Bacterial Colonization, Double-J Ureteral Stents

Countries: Egypt

This prospective cohort study will evaluate the risk factors associated with bacterial colonization of Double-J ureteral stents and examine its clinical implications. Adult patients undergoing temporary ureteral stent insertion for routine urological indications will be followed until stent removal, when urine and stent cultures will be obtained. The study will assess the association between colonization and factors such as indwelling time, diabetes mellitus, chronic kidney disease, prior urinary tract infection, prior antibiotic exposure, and stent-related symptoms.
